Post-traumatic Stress Disorder

Post-traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

Background:

Post-traumatic stress disorder (PTSD) is prevalent in military personnel, necessitating novel treatment strategies.
Virtual relaxation interventions, particularly 360-degree nature videos, show potential for reducing distress and hyperarousal in PTSD patients.
Existing research indicates relaxation effects of nature videos in healthy individuals, prompting investigation in PTSD populations.

Purpose of the Study:

To examine the relaxation effects of 360-degree nature videos for patients diagnosed with PTSD.
To compare the efficacy of head-mounted display (HMD) versus PC screen immersion levels for virtual relaxation.
To explore the impact of intervention dose duration (5 vs. 10 minutes) on relaxation outcomes.

Main Methods:

A counterbalanced, randomized, controlled, within-subject feasibility study with 36 participants (soldiers with PTSD).
Participants experienced HMD, PC, and sound-only control conditions for 5 or 10 minutes.
Collected self-reported relaxation, skin conductance, heart rate, and heart rate variability data; qualitative interviews were also conducted.

Main Results:

Feasibility study to provide initial evidence on the relaxing effects of 360-degree nature videos for PTSD patients.
Comparison of HMD and PC screen immersion levels against a control condition (natural sounds only).
Validation of intervention dose duration (5 vs. 10 minutes) for future trials.

Conclusions:

This study will offer preliminary data on the effectiveness of virtual nature videos as a relaxation tool for soldiers with PTSD.
Findings will inform the design of subsequent confirmatory interventional trials.
The research will guide the optimal use of immersive technologies in PTSD treatment.
